Welcome to MapNode Extension Wallet Developer Guide. This documentation contains guides for developers to get started developing on MapNode Extension Wallet.‌

To detect MapNode Extension with Ronin

To detect whether your browser is running MapNode Extension, please use:

if(window.MapNode || window.ethereum || window.ethereum?.isMapNode){
    console.log('MapNode Extension is installed!');
}

To connect MapNode Extension Wallet

To connect MapNode Extension means to access the user's [blockchain - like Ethereum] account(s).

// Connect & get accounts
window.ethereum.request({method: 'eth_accounts'});
// Alias for connection
window.ethereum.request({method: 'eth_requestAccounts'});​
//Check if dapp connected
window.ethereum.isConnected();

To disconnect MapNode Extension Wallet

To disconnect MapNode Extension, please use:

window.ethereum.disconnect()

To experience functions

Once your account is connected, let's start experiencing more functions.‌

Get Current Account

return Promise<Array[String]>

  • If wallet can not be found, return [] instead of throw Error

window.ethereum.request({ method: 'eth_accounts' }).then(accounts => {
  if (accounts[0]) {
    // Do something with accounts
  } else {
    // Wallet not found
  }
})

Check wallet whether exists or not

return Promise<{data: Boolean}>

window.ethereum.request({ method: 'has_wallet', params: ['ronin'] })
// Example
window.ethereum.request({ method: 'has_wallet', params: ['ronin'] }).then(() => {
  // Wallet Exists
}).catch(e => { 
  // Wallet not found
})

Sign

return: Promise<Signature | RPC: 2.0>

// Example Sign 
const signature = window.ethereum.request({
    method: 'eth_sign',
    params: [
     {
        "to": "string",
        "gas": "string",
        "gasPrice": "string",
        "value": "string",
        "data": "string",
        "nonce": "string"
     }
    ]
});

window.ethereum.request({
  method: 'eth_sendTransaction',
  params: [
    {
      'to': 'string',
      'gas': 'string',
      'gasPrice': 'string',
      'value': 'string',

To handle events

List of events

Currently we only support some action event from wallet extension

window.ethereum.on('event_name', callback);
​//Example
window.ethereum.on('close', () => window.location.reload());
window.ethereum.on('accountsChanged', () => window.location.reload());
